噻唑环系的化合物人们非常熟悉,如具有杀菌药效的磺胺噻唑和有阻止链球菌生长效能的青霉素及其衍生物。但在这五员杂环中,再引进一个氮原子成为噻唑环系及其衍生物,则相应地研究较少。现把2—氨基—1、3、4—噻二唑及2—氨基—5—巯基—1、3、4—噻二唑的合成及其生物效应的初步实验以及某些衍生物的合成实验的结 The thiazole ring system compounds are well known, such as bactericidal efficacy of sulfathiazole and have to stop the growth of Streptococcus penicillin and its derivatives. However, in this five-membered heterocyclic ring, the introduction of a nitrogen atom into the thiazole ring system and its derivatives, the corresponding study less. The synthesis of 2-amino-1,3,4-thiadiazole and 2-amino-5-mercapto-1,3,4-thiadiazole and the preliminary experiments of their biological effects, as well as the synthetic experiments of some derivatives Knot
